Lung Function Tests or breathing tests are a really useful way for me to assess your lung capacity and tell you how well your lungs are functioning. These will generally involve you blowing into a machine as hard as you can whilst wearing a nose clip (so that air doesn’t escape from your nose).
Once you have done your lung function tests, the physiologist who does them will send them to me the same day. These tests are done at the Cromwell Hospital (SW5) or the Harley Street Clinic (W1).
